If your Remote Access server has port 80 open but is not using the standard HTTPS port 443, and HTTPS redirection (Force HTTPS) is enabled, the Let’s Encrypt validation may fail.


To help with this, we have a solution that lets you bypass HTTPS redirection only for the specific path Let’s Encrypt uses to validate the token on your server. This allows the Let’s Encrypt validation request to remain over port 80 while the rest of your site can continue using HTTPS redirection as expected.



Instructions:

  1. Add the following line to the *\Clients\webserver\settings.bin file in your TSplus directory:
    allow_http_while_no_ssl="/.well-known/acme-challenge/"
  2. Restart the web server using the refresh icon on the AdminTool > Home screen
